Emergency Response Guidebook (ERG, 2016)

UN/NA datasheets display several items from the ERG: material names,
response guide PDFs, initial isolation and protective action distances,
warnings about toxic-by-inhalation gases that may be produced if the
material spills in water, and polymerization hazards.

Hazmat Table (49 CFR 172.101)

The
Hazmat Table
in 49 CFR 172.101 "lists and classifies those materials which the
Department (of Transportation) has designated as hazardous materials
for purposes of transportation".

UN/NA datasheets display several items from the Hazmat Table: proper
shipping names,
hazard classes and divisions
(explosives may also include a
compatibility group letter),
label codes, and special notes relating to shipping location, shipping
name, and whether the material is an inhalation hazard.

Descriptive text for each label code is shown below the table, along
with representative
vehicle placards.
